Tech Help!!! for company Scion xb

[tiksman]

I have a xb that belongs to my company. The dumb driver blew the engine. The #4 rod had knocked a hole in the oil pan and both sides of the block.
Anyway,
Put in a used engine and the starter wont engage correctly.
There is a dent in the starter where a chunk of the block hit it.
There also was metal shavings in the bellhousing and starter.
I cleaned out the starter and the bellhousing (took the starter apart)
I thought everything was good but.... I NEED HELP.
Could someone with a automatic and mechanical know-how remove the plastic inspection cover that covers the flexplate and tell me or take a photo of the flexplate teeth. I need to know if you can see the welds on the flexplate to the teeth or if there is a 1/4 inch lip on the teeth to the flexplate. If so I put the darn flexplate on backwards . If not I have a bad starter.
I also posted on the xb board but the yaris has the same engine, And I have been here b4.
